Command request: "Save image As" and "Search selection"

It would be awesome to be able to map the "Save Image As" to a mouse gesture to optimise workflow.
Being a 3D artist, I tend gather reference images quite often, and saving those few clicks adds up to a lot of time and nerve saving.

Sane for the "Search selection"

Both commands are already present in the right click menu ("Save image as..." and "Search for "x" " )

So it's just a matter of making them available in the mappable command list.

PS: Similarly, just making a list of command script in a documentation page and allowing us to manually add those scripts as mappable shortcuts (either mouse or keyboard) would be even more awesome for advanced users.
